Question

jezelyn needs to create a project that shows geographic isolation in action and decides to make a video. which of these would make the best project? a video that shows penguin species that have different mating dances a video that shows a large river that has penguin populations on both sides a video that shows a penguin that is laying eggs a video that shows penguins with different reproductive cycles living together

Explanation:

Geographic isolation occurs when a physical barrier separates a population. A large river separating penguin populations is a physical - barrier example. Mating dances and reproductive cycles relate to reproductive isolation, not geographic. Laying eggs is a normal reproductive behavior not related to isolation.

Answer:

a video that shows a large river that has penguin populations on both sides
